In order to better study an X-ray binary, multi-wavelength
counterparts to the X-ray source must be identified to allow
determination of, e.g., distances, energy distribution, and
evolutionary phase. For instance, infrared observations can
reveal the presence of eclipses, modulations (due to, e.g.,
orbital periods), variability, etc., allowing us to better
constrain the true nature (e.g.: High-Mass or Low-Mass?) of
the binary system. In this work we'll discuss the status of
an ongoing project in Brazil to identify Infrared
counterparts of INTEGRAL X-ray sources. We'll discuss some
preliminary results for a dozen (or so) sources and
illustrate our search and data analysis with IGR
J16320-4751. Future steps of this (and similar) research
using the modern 4{\thinspace}m SOAR telescope are also
highlighted. This work is partially supported by
FAPESP/Brazil.
